To all whom it may concern: I

Be it known that I, WALTER W. MARSH, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented. certain new, and useful Improvements inCloset-Traps, of which the following is a specification.

The device which is the subject matter of the present application for patent is designed to prevent obstructions passing down the bowl of acloset and lodging in the waste pipe or in the trap, and the invention has for its object to provide a novel and im proved float-controlled valve whereby this object'is attained.

.The invention also has for its object to provide a device of the kind stated which can be readily applied to the closet bowl without. any alteration in the structure thereof. a

In order that the invention may be better understood, reference is had to the accompanying drawing, in which i Figure 1 is a vertical section of a closet bowl showing the device mounted in place therein; Fig. 2 is a vertical section of the device, and Fig. 3 is a plan view thereof.

In the drawing, 5 denotes an ordinary closet bowl having a hinged lid 6, and a flushing inlet 7. In the lower portion of the bowl, below the flushing inlet, and a short distance above the connection of the bowl with the waste pipe 8, is mounted a support 9 for a flap valve 10, said valve being substantially semicircular in outline, and having along its free edge a row of perforations 11. The valve support is a ring of inverted, substantially frusto-conical contour to fit snugly in the bowl, the outer surface of the ring having a groove to receive and hold a packing ring 12 whereby a tight fit is obtained. The valve is inside the ring,

mechanism and pivoted or hinged thereto, as shown at 13, and the ring has an inner marginal flange 14: forming a seat for the valve. The valve swings upward to engage the seat, and its opening movement is downward.

That portion of the ring 9 which is not occupied by the valve 10 has a lid 15 seating on top of the ring and provided with perforations 16, said lid being hinged to the ring as indicated at 17. That portion of the ring 9 which is covered by the lid 15 has a chamber 18 depending a short distance from the ring, and having connected to its lower end a pipe 19 forming a float chamher, there being a small outlet aperture 20 m the bottom of said chamber. In the float chamber is mounted a float 21 connected at i its upper end by a pivoted link 22 to an arm 23 made fast to and depending from the under side of the valve 10. The connec tion between the float and the valve is such that, whenthe float rises the valve swings open, and when the float descends the valve swings upward and closes against the seat 14. As the float chamber is normally empty of water, it will be seen that the valve is normally in closed position. Theinner wall of the chamber 18 has an aperture 24 through which the valve arm 23 extends.

In operation, the matter deposited in the bowl 5 drops on the valve 10, and remains thereon until the valve opens, which takes perforationslG into the float chamber 19,

and as the float 21 rises, the valve tilts down ward and allows the matterto drop and escape down the waste pipe 8. The diameter of the float chamber is such that it takes up but very little space in the waste pipe so as not to impede the free passage of the matter down the same. The float chamber fills before the flushing flow stops, leaving enough water to wash off the valve before the flushing action ceases. The water which has entered the float chamber to operate the float slowly escapes through the outlet 20, and as the float now descends it shuts the valve. A further flow of flush water escapes past the valve by the way of the perforations 11. This flow, together with the water escaping from the float chamber, provides the necessary after-flow to reseal the trap of the waste pipe. The perforations 11 also allow the escape of liquid from the bowl without openingthe valve 10.

It will be evident from the foregoing that the device serves as a trap to prevent rags and other obstructions which may be thrown into the bowl from passing down to the waste pipe, and all danger of the waste pipe or the trap being stopped up is obviated. If any obstructions are thrown into the bowl, they lodge on the lid 15 or the Valve 10, from which they can be readily removed.

The device can be applied to any ordinary closet bowl without any alteration in the structure thereof, and by the conical shape of the ring it can be tightly wedged in the bowl so that it is held in place without any fastening devices. The device can also be readily removed from the bowl.

While the preferred embodiment of the in- I vention has been shown, it will be understood 7 bowl having a flush water inlet; of a ring seating'in the bowl below the flush water inlet and having a valve seat, a downwardly opening valve engageable with the seat and pivoted to the ring, a depending float chamber carried by the ring and having a bottom outlet, a closure for the upper end of the float chamber earned by the ring, said closure having water inlets and closing a portion of the ring, the aforesaid valve closing the remaining portion of thering, a float in the float chamber, and an operative connection between the float and the valve for opening the valve when the float rises and closing the valve when the float descends.

2. The combination with a water closet bowl having a flush water inlet; of a ring removably mounted in the bowl below the flush water inlet and having a valve seat, a

,o downwardly opening valve engageable with the seat and pivoted to the ring, a depending float chamber carried by the ring and having a bottom outlet, a closure for the upper end of the float chamber carried by the ring,

said closure having water inlets and closing a portion of the ring, the aforesaid valve closing the remaining portion of the ring, a float in the chamber, and an operative connection between the float and the valve for opening the valve when the float rises and closing the valve when the float descends.

3. The combination with a water closet bowl having a flush water inlet; of a ring seating in the bowl below the flush water inlet, a hinged lid and a pivoted valve carried by the ring and closing the same, the lid being perforated and the ring having a seat for the valve, a float chamber below the lid and having a bottom outlet, a float insaid chamber, and an operative connection between the float and the valve for opening the valve when the float rises and closing the valve when the float descends.

In testimony whereof I aflix my signature in presence of two witnesses.
